At present, there are two standards for 3PE anti-corrosion steel pipes, namely GB/T 23257-2009 and GB/T 23257-2017. GB/T 23257-2017 is a new standard, implemented in December 2017. The two standards differ mainly in the following ways:3PE anti-corrosion steel pipe1. The design temperature of the ant

Welding equipment: ZX7-400-3 welding machine is used for root welding; Kumagai ZD-500 multifunctional steel pipeline automatic welding equipment is used for filling and covering.Welding material: Bole φ3.2 E6010 cellulose electrode is used for root welding; Lincoln E81T8-G φ2.0 flux-cored self-shiel

There are roughly four types of spiral pipes according to their uses: spiral pipes for drainage, spiral pipes for dredging, spiral pipes for piling, and spiral pipes for oil and gas.Spiral pipe for drainage: Material of spiral steel pipe for drainage: Q235A, Q23b, 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9,

Anticorrosion of the inner wall of large-diameter steel pipes:1. Before processing all steel pipes, the steel plate on the inner wall side of the large-diameter steel pipe shall be de-rusted until the metal is exposed to metallic luster (whitening). It should meet the sa2.5 standard required in GB89

Liquid epoxy coating is a coating system composed of two substances. It is mainly applied on floors and gives off a unique finish compared to traditional coatings because of its distinct chemical composition.Product name: Epoxy Coated PipeSize: 260mmX3mmX12000mmStandard: AWWA C210

If the spiral steel pipe for water transportation is used to transport tap water or drinking water, the inner wall is usually made of IPN8710 non-toxic anti-corrosion coating, and the outer wall is made of epoxy coal tar pitch for anti-corrosion. Of course, it can also be used for inner and outer pl

Cooling form of large diameter steel pipe:Large-diameter steel pipes are steel pipes with an outer diameter of 1000MM or more. Large-diameter seamless steel pipes are made of steel ingots or solid tube blanks that are perforated into capillaries, and then hot-rolled, cold-rolled, or cold-drawn.1. Ch

As a terminal technical product of the steel pipe industry chain, anti-corrosion steel pipe has always occupied a very important position in the industry. In recent years, with the development and application of new anti-corrosion technologies for steel pipes, anti-corrosion steel pipes have become

Stainless steel pipe is a hollow long strip of steel, which is widely used as a pipeline for transporting fluids, such as oil, natural gas, water, gas, steam, etc. Stainless steel pipes are lighter in weight when they have the same bending and torsional strength. They are widely used in the manufact

①General boiler steel tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes, and arch brick tubes, etc.②High-pressure boiler steel tubes are mainly used to manufacture superheat
